I have other shots of this beauty that are more convincing to lead me to the conclusion that this is a female Hooded Merganser. But that bright golden eye threw me. So I wondered, could it be some sort of Goldeneye? The bill and the body coloration are more of the Merganser, so I am going with that, unless someone has a better idea, that is! :) I liked the colors and the light in the scene at Alton Baker Park.
